ip6 for VM

[diversity]

using virt machine manager 3.2.0
on a debian 11 host running a gnome desktop

I'd like to have the VM's get a global ip6 address.

The host is getting a global ip6 address from the DHCP server through a 
wireless access point that creates a 'wlp4s0' interface on the host.

To confirm the ip6 is indeed global I first use
ip a to see what is the global ip6 address with scope global dynamic 
noprefixroute on the host.
Then see if that ip6 address is detected when visiting whatismyip.com 
using a browser on the host and the detected ip6 address matches the 
global ip6 address listed using ip a command

I have 3 options in the virt manager GUI for networking options
NAT, Bridge, Macvtap device

NAT, if I am not mistaken, is IP4 so not relevant.
Bridge with 'wlp4s0' as device name result in this error.

"

Macvtap device, with 'wlp4s0' as device name does not result in an 
error. However what ever I try in the VM (ubuntu 20.4 desktop) no ip6 
lease is being gotten.

Can anyone please direct me to documentation on how to set this up? or 
perhaps if documentation does not exist yet give some hints on how to 
proceed?
